I can understand it being sad, in a way, that they are thinking about moving it...but it sounds like for YOU and YOUR family it's the best thing. I know Ethan loves them being there, but all the extra arguing and stress isn't good for him either. I'm sorry it hasn't been working out
And you are NOT weak for having ppd! There is no weak about that, though I know a lot of people don't understand. Have you thought about going in to talk to your ob about it?
